Is Naperville a Good Place to Invest in Rental Property?

Naperville, IL has a population of 150,000 and has been growing at 0.5% annually — roughly in line with national trends, meaning demand is stable but not exceptional. The median home price of $440,000 paired with median rents of $1,950/mo produces an estimated cap rate of 2.29%.

Property taxes at 2% are notably high and represent a significant drag on cash flow — model this expense carefully, as it can make or break a deal. The vacancy rate of 4.2% is impressively low, indicating tight rental supply and strong tenant demand — favorable for landlords.

At a price-to-income ratio of 3.7x, homes cost about 3.7 times the local median income of $118,000. This relatively affordable ratio suggests a deep pool of renters who find buying out of reach, supporting rental demand. Home values have appreciated at roughly 2.5% annually. Steady appreciation means total returns will be primarily cash flow-driven — the more sustainable model for long-term wealth building.

Bottom line: At current median prices, Naperville is challenging for pure cash flow investing. Consider BRRRR strategies with below-market purchases, or look at neighboring metros with stronger price-to-rent ratios.
